Heat sink clip

Abstract

A heat sink clip ( 30 ) includes a spring portion ( 31 ) and two arms ( 36 ) extending from respective opposite ends of the spring portion. The spring portion has a horizontal portion ( 35 ) which forms a tab ( 33 ) extending horizontally and then downwardly from a side edge of the horizontal portion. The tab defines a positioning hole ( 34 ) for engaging with a catch ( 62 ) formed on a side wall of a retention module ( 60 ). Each arm defines an aperture ( 37 ) for engaging with a beam ( 61 ) formed on each end of the retention module. The end of each arm extends outward to form a T-shaped handle ( 40 ). The handle includes an L-shaped connecting portion ( 41 ) and an L-shaped operation portion ( 42 ).

What is claimed is:  
     
       1. A heat sink clip comprising: 
       a spring portion;  
       a pair of arms extending downward from respective opposite ends of the spring portion; and  
       a pair of handles respectively extending outward and upward from distal ends of the arms;  
       wherein each handle comprises an L-shaped connecting portion extending from each the arms, and an L-shaped operation portion extending from the connecting portion.  
     
     
       2. The heat sink clip as described in  claim 1 , wherein the spring portion comprises a horizontal portion and a tab extending downward from one side of the horizontal portion. 
     
     
       3. The heat sink clip as described in  claim 2 , wherein the tab defines at least a positioning hole adapted to engage at least a catch of a retention module. 
     
     
       4. The heat sink clip as described in  claim 1 , wherein each handle is generally T-shaped. 
     
     
       5. A heat sink assembly comprising: 
       a heat sink;  
       a device positioned under the heat sink and adapted to be secured to a printed circuit board thereunder;  
       a clip positioned around a first edge of the device and against the heat sink, said clip including a spring portion with a pair of arms downwardly extending from two opposite ends thereof and latchably engaged with opposite first and second sides of the device, respectively, and a tab downwardly extending from a position of the spring portion between said pair of arms and engaged with a third side of the device; wherein  
       a pair of handles respectively extends outwardly and upwardly from the arms.  
     
     
       6. The assembly as described in  claim 5 , wherein said third side is perpendicular to said first and second sides. 
     
     
       7. The assembly as described in  claim 5 , wherein said tab is perpendicular to said pair of arms. 
     
     
       8. The assembly as described in  claim 5 , wherein said heat sink is directly seated upon the device. 
     
     
       9. The assembly as described in  claim 5 , wherein said third side includes means for locking the tab in position. 
     
     
       10. The assembly as described in  claim 5 , wherein another clip is positioned around a second edge of the device opposite to the first edge. 
     
     
       11. A heat sink clip for use with a retainer module and a heat sink, comprising: 
       a spring portion;  
       a pair of arms downwardly extending from two opposite ends of the spring portion for engaging with the retainer module;  
       a pair of handles respectively extending outwardly and upwardly from the arms; and  
       a tab downwardly extending from one side of the spring portion between said pair of arms.  
     
     
       12. The heat sink clip as described in  claim 11 , wherein the spring portion includes a horizontal portion from which the tab extends. 
     
     
       13. The heat sink clip as described in  claim 11 , wherein both said pair of arms and said tab define locking openings therein for latchable engagement with the retainer module. 
     
     
       14. A heat sink assembly comprising: 
       a heat sink;  
       a device positioned under the heat sink and adapted to be secured to a printed circuit board thereunder, said device defining opposite first and second side each with a locking beam thereon;  
       a clip positioned around a first edge of the device and against the heat sink, said clip including a spring portion with a pair of arms downwardly extending around two opposite ends thereof and latchably engaged with the corresponding locking beams of the device, respectively, and a tab downwardly extending from a position of the spring portion between said pair of arms and engaged with a third side of the device; wherein  
       a pair of handles are respectively positioned beside the corresponding arms, and prevent said corresponding arms and the associated locking beams from being exposed to an exterior in a transverse direction.  
     
     
       15. The assembly as described in  claim 14 , wherein said arms directly extend from two opposite ends of the spring portion and the handles extend from the corresponding arms, respectively. 
     
     
       16. The assembly as described in  claim 14 , wherein each of said handles includes an L-shaped connection portion upwardly extending from the corresponding arm. 
     
     
       17. The assembly as described in  claim 16 , wherein each of said handles further includes an L-shaped operation portion extending from the connection portion, and creates an mirror image with regard to said connection portion.
